Izinto zogwebu ze-EVA

I-EVA lolona luhlu lwesine ngobukhulu lwe-ethylene lwepolymer emva kwe-HDPE, i-LDPE kunye ne-LLDPE.Xa kuthelekiswa nezinto zemveli, ixabiso layo liphantsi kakhulu.Abantu abaninzi bacinga ukuba imathiriyeli yogwebu ye-EVA ludibaniso olugqibeleleyo lweqokobhe eliqinileyo kunye neqokobhe elithambileyo, ligcina izibonelelo zegwebu elithambileyo nelilukhuni ngelixa lishiya izinto ezingeloncedo.Kwakhona, ukuguquguquka okungokwemvelo kuyilo lwemathiriyeli kunye nobuchule bokuvelisa ikwayeyona nto iphambili kwezinye iinkampani eziphambili zehlabathi kunye neebrendi ezijikela kwi-EVA foam xa umgangatho ophezulu, imathiriyeli yokwenziwa kwexabiso eliphantsi kufuneka.

Ngaphezu kokubhetyebhetye, imathiriyeli yogwebu ye-EVA ikhathalela ubomi bethu bemihla ngemihla kunye nemisebenzi yeshishini, kwaye ibangele inkoliseko yabasebenzisi bokugqibela.Izihlangu, amayeza, iipaneli ze-photovoltaic, ezemidlalo kunye neemveliso zokuzonwabisa, iithoyi, umgangatho / iimethi zeyoga, ukupakishwa, izixhobo zonyango, izixhobo zokukhusela, wat

Iimveliso zezemidlalo zikwimfuno eyomeleleyo yeemveliso zeplastiki ezihlala ixesha elide, kwaye icandelo lemakethi ye-EVA ye-foam iyaqhubeka nokuzisa ukukhula okutsha kwe.

丨EVA iipropati zomzimba kunye nezoomatshini

Iipropathi ze-EVA copolymers zichongwa ngokukodwa ngumxholo we-vinyl acetate kunye neqondo lokumanzi.Ukunyuka komxholo we-VA kwandisa ubuninzi, ukucaca kunye nokuguquguquka kwezinto eziphathekayo ngelixa kunciphisa indawo yokuncibilika kunye nobunzima.I-ethylene-vinyl acetate copolymer (i-EVA) yimpahla enwebeka kakhulu enokuthi ifakwe i-sintered ukuze yenze i-raber efana ne-foam, kodwa inamandla abalaseleyo.Iguquguquka ngokuphindwe kathathu kune-low density polyethylene (LDPE), inobude be-tensile obuyi-750%, kwaye inobushushu obuphezulu bokunyibilika obuyi-96°C.

Ngokuxhomekeke kwizithako kwinkqubo yokuvelisa, iidigri ezahlukeneyo zobulukhuni be-EVA zinokufezekiswa.Kubalulekile ukugcina inqanaba eliphakathi lobunzima kuba i-EVA ayibuyiseli imilo yayo emva koxinzelelo oluqhubekayo.Xa kuthelekiswa ne-EVA enzima, i-EVA ethambileyo ayixhathisi kangako kwi-abrasion kwaye inobomi obufutshane kwindawo yodwa, kodwa ikhululekile ngakumbi.

丨 EVA iipropathi thermal

I-melting point ye-EVA iyancipha ngokunyuka komxholo we-VA.Ngoko ke, ukushisa kokusetyenziswa kwe-copolymer kuphantsi xa kuthelekiswa ne-homopolymer ehambelanayo (LDPE).Ubushushu obuphezulu bokusebenza kwendawo yokusebenza bungaphantsi kobushushu bokuthambisa iVicat.Njengazo zonke iipholima ze-thermoplastic, ubushushu buxhomekeke kubude kunye nenqanaba loxinzelelo lomatshini apho i-workpiece iphantsi kobushushu.Njengoko iqondo lobushushu landa, iqondo lobushushu conductivity iyancipha de ifikelele kwithafa kufutshane kwindawo yokunyibilika.
